I've been on double dose of Testogreens Max for 3 months now. My energy level, mental sharpness are off the charts. I keep losing fat/weight, and I haven't even started working out yet. I'll never go without it. It's an amazing supplement. I'm 65 yrs old and I feel like I'm 45. If you're on the fence, get some, you won't regret it. Best money I've spent.
